The above graph is presents data from the historical database. The historical database does not contain county-level data for July 14, 2020. I am aware that COVID-19 data collection policies have changed, but I do not know whether these events are related.
The live database still seems to be receiving updates.
The current version of the code uses the historical database. Adapting the code to pull data from the live database should be possible but, due to technical differences in the way the data is presented, would take some time.
Hopefully the historical database will resume updates within a few days. If not, and if the live database is still receiving updates, then I will explore modifying the code to use the live database.
